Rose plant -- Meiponal variety

ABSTRACT

A new and distinct variety of rose plant of the Miniature Class is provided which forms abundantly and continuously highly attractive semi-double blossoms. The blossoms are light ochre yellow on the upper surface and pale buttercup yellow on the under surface. The plant is well suited for pot forcing and forms attractive ornamentation when grown as a flowering pot plant either indoors or outdoors.

SUMMARY OF THE INVENTION

The new variety of Miniature rose plant was created by artificial pollination wherein two parents were crossed which previously had been studied in the hope that they would contribute the desired characteristics. The female parent (i.e., the seed parent) was the product of the pollination of the Meihand variety (non-patented) by the Moulin Rouge variety (U.S. Plant Pat. No. 1,298). The male parent (i.e., the pollen parent) of the new variety was the product of the pollination of the Meialfi variety (non-patented) by the Meikim variety (non-patented). The parentage of the new variety can be summarized as follows:

    [Meihand×Moulin Rouge]×]Meialfi×Meikim].

The seeds resulting from the above pollination were sown and 197 plantlets were obtained which were physically and biologically different from each other. Selective study resulted in the identification of a single plant of the new variety.

It was found that the new variety of Miniature rose plant of the present invention possesses the following combination of characteristics:

(a) forms in abundance on a continuous basis attractive semi-double blossoms which are light ochre yellow on the upper surface and pale buttercup yellow on the under surface,

(b) exhibits a bushy growth habit, and

(c) is well suited for pot forcing.

The new variety well meets the needs of the horticultural industry for many usages. It is particularly well-suited for use as attractive ornamentation as a flowering pot plant for use indoors or outdoors.

The new variety has been found to undergo asexual propagation by a number of routes, including budding, grafting, cuttage, etc. The characteristics of the new variety have been found to be strictly transmissible by such asexual propagation from one generation to another.

The new variety has been named the Meiponal variety, and is being marketed by The Conard-Pyle Company under the Sunny Sunblaze trademark.

DETAILED DESCRIPTION

The chart used in the identification of the colors is that of The Royal Horticultural Society (R.H.S. Colour Chart). The terminology which precedes reference to the chart has been added to indicate the corresponding colors in common terms. The description is based on one year old specimens of the new variety during June while growing on their own roots outdoors at Cannet-des-Maures, Var, France.
